在多年野外物种考察基础上,依据河北大学馆藏标本和文献资料,对河北省的芫菁种类进行分类和整理,共计9属24种,其中丽斑芫菁Mylabris(Chalcabris)speciosa(Pallas,1781)、四星栉芫菁Megatrachelus politus(Ge-bler,1832)、二斑狭翅芫菁Stenoria(Stenoria)fasciata (Faldermann,1835)和异色带栉芫菁Zonigis fortuccii Fairmaire,1887为河北省新纪录种,并编制了属、种检索表.记述了各种的地理分布.     

Synopsis of Falsocis Pic (Coleoptera, Ciidae), new species, new records and an identification key

Three new species of Falsocis Pic are described: Falsocis aquiloniussp. n. from Panamá, Costa Rica and Colombia, Falsocis egregiussp. n. from a single locality in northern Brazil and Falsocis occultussp. n. from two localities in southeastern and southern Brazil. New records, comparative notes and an identification key for male and female specimens of Falsocis species are also provided.     

A Taxonomic Note on the Little Known Family Prostomidae in Korea (Coleoptera: Tenebrionoidea)

A taxonomic study of the Korean Prostomidae is presented. Two species (Prostomis latoris Reitter, P. mordax Reitter) are recognized and P. mordax is reported for the first time in Korea. Comparison with type specimens was made. An illustration of the habitus and line drawings of diagnostic characters are provided.     

Phylogeny of European Pyrochroa (Coleoptera,Pyrochroidae) reveals cryptic taxa and different glacial histories

Only three saproxylic species of Pyrochroinae (Coleoptera: Pyrochroidae) are distributed in Europe, two of which belonging to Pyrochroa: P. coccinea and P. serraticornis. However, P. serraticornis is polytypic, for the presence of the endemic subspecies P. s. kiesenwetteri in southern Italy. Using both molecular and morphological data, we explored the phylogeny of the European Pyrochroa species. A multilocus (COI, CAD, 28S) phylogenetic analysis helped highlight different evolutionary histories for the two examined species. First, P. coccinea, distributed throughout Europe, showed a high differentiation among Italian and European populations. Furthermore, three different taxonomic entities were identified within P. serraticornis, among which the cryptic species Pyrochroa bifoveata sp. n. from central Europe is described and illustrated. A comprehensive identification key to the European Pyrochroinae is also provided. Our results also suggested an historical survival of P. coccinea and P. s. kiesenwetteri in glacial refugia in Italy, and a subsequent post-glacial spread of the former species throughout the Peninsula. In contrast, the current distribution of P. s. serraticornis likely originated from a post-glacial colonization of western European relict populations, while the survival of P. bifoveata plausibly occurred in more eastern glacial refugia (e.g. Carpathian or Balkan regions). Similarly, the European populations of P. coccinea could have originated from relict populations in glacial refugia out from the Italian Peninsula. More comprehensive data on the taxonomy, ecology and biogeography of Pyrochroa are needed to learn more about these species and to help preserve the European saproxylic fauna.
